SPECIFICATION forming part'of Letters Patent No. 298,161, dated May' 6, 1884-.

` Application filed August 30, 1883.

To all whom it may concern:

Be it known that I, ACHILLE BERTELLI, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Soda-Tater Apparatus, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved apparatus for making car-v bonic-acid gas and mixing the same with water, for the purpose of making aerated waters.

The invention consists in an apparatus for generating carbonicacid gas,which apparatus is adapted to be placed directly on a fountain, or can be coupled with a series of fountains for charging the water in the fountains with gas.

The inventionl also consists in numerous parts and details of construction of a generator, as will be fully described and claimed herei n after.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Fig. 2 is an enlarged detail longitudinal sectional elevation of the tube in the gas-generator. Fig. 3 is au enlarged detail sectional view of the safety-valve of the generator. Fig. 4 is an enlarged sectional view of one of the plugs of the fountain. Fig. 5 is an enlarged detail sectional View of the lower part of the gas-washer and the upper part of the fountain. Fig. Gis a like view of the upper part of the fountainspoutand the fountain after the fountain has been detached from the washer and generator. Fig. 7 is a detail ele* vation of the valve ofthe fountain. Fig. 8 is a sectional plan view of the same on the line x x, Fig. 7. Fig. 9 is a general perspective view .detail view of/.the valve E.

rllhe fountain A is made of two sections, AA `A2, tinned on the inside, andprovided with iianges a, which are bolted together by bronze bolts a',A gutta-percha packing-strips a2 being placed between the flanges. The iiauge of the bottom section, A2, is bent down at the outer edge to form a base for the fountain. The

(No model.)

fountain is provided with suitable bronzehandles, a3.

The generator and washer Bjconsists of a copper vessel, Blined with tin, and provided at its upper end with an outwardly-'projecting flange. A smaller copper vessel, B2, of about half the depth of the vessel B', is also provided at its upper end with an outwardly-projecting fiange, the vessel B2 being within thevessel B, and the vessel B- being lined with lead and covered on the outside with tin. The generator B. is provided with a' bronze cover, B3, resting 'on the fiange of the vessel B2, the said cover being held on the generator by bolts b, passed through the cover and through the flanges 'of the vessels B B2, suitable packingrings, b', being interposed between the cover and the flanges, as shown.

The acid box C consists of a heavy bottleshapedleaden vessel. C', contained in a bronze cupshaped vessel, C2, provided with a slightly-concave screw-cover, C3, between which and the upper edge of the vessel CZapacking-ring, c, is interposed. The leaden vessel C is pro'- vided in its bottom with small projections c2, which are to prevent the bottom ofthe leaden vessel from coming in contact with the outer bronze vessel, G2. The vessel C" terminates Lat the bottom in a screw-collar, d, which is not screw-threaded to the end, but is left plain for about half its length-thatis, from the middle to the lower end, the part which is not screwthreaded having a greater internal diameter than the, screw-threaded part. Vhere the threaded part and the plain part meet a shoulder, d', is formed. The cover B3 ofthe generator B is provided with a neck, B", the upper part of which is screw-threaded, and the lower part is left plain and of a larger diameter, a shoulder, b2, being formed where the screw-threaded part and the plain part meet. A packingring, cl2, of guttapercha, rests on the shoulder b2, anda packing-ring, d, of a circular crosssection, is placed in an annular groove in the plain part of the neck B", directly below the shoulder b2, so that when the collard is secured on the neck B", the plain part'of the collar d IOO will compress and flatten the ring d3, as shown.

E, provided at its upper end with a funnell shaped recess, e, from which a vent, c', is inclined downward toward the outer surface of the tubular valve. At its upper end the tubular valve E is provided with an annular ridge, E', on the top and bottom of which asbestus packing-rings L2 are held. A tin screw-collar, D', is screwed on the lower end of the collar D, and is provided with a shoulder, D2, on which an annular ilange, F', rests, which is formed on the upper end of a leaden tube, F, whereby, by screwing the collar D' on the collar D, the llange F' at the upper end of the tube F will press against the bottom packingring l2 of the annular ridge E' on the valvetubc E, and will press the top packiiigring, E2 against the bottom edge ot' the neck G of the leaden vessel C'. A silver tube, F', is soldered to the lower end of the leaden valvetube E, which silver tube l12 is provided with a vertical longitudinal slot, F', and has its lower end screw-threaded internally, in which screw-threaded part a silver screw-cap, G', is screwed, in the upper end of which a silverplated copper rod, G, is held by a ball andsocket `joint` which rod extends up through the valve-tube E, the inner diameter of which is greater than the diameter of the rod G, ex cept at bottom ol' thevalve-tube E, which bottom opening is of such size that the rod G iits closely therein. In thebottom ofthe valve-tube E vertical slots are formed, as shown in Fig. 1l. A leaden ball, G``, is secured on the up per end of the rod G, and fastened by a drop of solder. The silver screw-cap G'is soldered on the upper end of a loaden rod, H, which is provided with a channel, H', by which communication is established between the exterior and the interior of the said silver cap G'. rlhe bottom ofthe leaden tube F does not rest on the bottom of t-he vessel B2, but terminates a short distance above the saine, and the said bottom edge of the tube F is provided with a series of washers, F".

On a neck formed on the cover B ol' the generator an internally-tinncd bronze cap, J, is secured, and in the cap J an inverted copper cup, J', is screwed in such a manner that the opening of the cup will be at the bottom, and a small space will be lett between the inner side of the cap J and the outer side of the cup J On atubular arm ofthe cap J a screw cap, J 2, is screwed,which forms a safety-valve, in which cap J2 a silver plate, J is held by a plug, J provided with two apertures, j. A needle-hole, g, establishes communication between the space formed in the interior of the tubular arm of t-he screw-cap J and t-he space between the screw-cap J and the cup J The generator-fountain and the acidbox must always beso constructed that they can resist a pressure of twenty-five atmospheres, and the silver plate J i must be so constructed that it can resist a pressure of fifteen atmospheres. The cap J, the plug J*, and the cup J are all provided with suitable packing-rings. A tin pipe, K, is provided at its upper end with an external scre\\'thread, thc upper end of the pipe K projecting into the cup J'. The pipe l is soldered in a longitudinal recess or groove, K', formed in the vessel B, and its lower end is soldered to a perforated tin box, K2, on the bottom ot' the vessel B', and provided with a suitable aperture through which a tin pipe, L, passes, which is soldered to the upper end of an internally-threaded neck, L', passed into and projecting from the bottom ol' the vessel B', as shown in Fig. 5. A bronze spout, Bf, tinncd inside, projects upward from the side ot' the vessel B', and is closed by a screw plug, B, provided with a suitable handle. An internally-threaded circular tin block` M, is secured to the under side of the top ofthe fountain,\vl1ieh block tapers toward the bottom and terminates in a downwardlyproj ecting neck, M'. At the upper end ofthe neck an annular groove is formed, in which a gutta-percha packing-ring, m, is placed. A circular tin block, N, is screwed in the block M, and is provided at its top with an externally-threaded neck, N', which is screwed in the threaded aperture of the neck L', provided on the bottom of the vessel B', a packing-ring being placed on the upper end of the neck N'. Bronze rings m' are passed around the neck M' of the block M and around the neck L. The block N is provided with a longitudinal cent-ral aperture, Nwhich is adapted to communicate with the tin tube L in the vessel B'. The block N is provided in its bottom with a circular recess, N3, into which an externallyscrew-threaded neck, Nt, ot' block N extends, on which the upper end of a tin pipe, O, is screwed, which is contracted a short distance below its upper end and forms a shoulder, O', the said pipe O extending to within a short distance of the bottom ofthe fountain. In the wider upper part ofthe pipe O a cylinder, l), is contained, which is provided with a head, l", at the top and a head, P2, at the bottom, the diameter of the cylinder P being less than the internal diameter ofthe wider part of the tube O. The upper head, F', of the cylinder l? is covered by a rubber cap, P, provided with a central aperture, p, which is directly above a longitudinal aperture, l, in the middle of the cylinder l?, the said aperture l." extending down to within about one-third ofthe length of the cylinder from the lower end of the said cylinder. A vertical segmental recess, Q, is formed in the outer edge of the cylinder l), and from the said recess a series of horizontal apertures, Q', extend to the longitudinal aperture I" of the cylinder, thus establishing` communication between the exterior and interior of the cylinder. An india-rubber tube, Q2, is passed around the outside of the cylinder P, and extends about one-eighth ol' an inch beyond the ends of the recess or groove Q, and is held in place by tin buttons Q, projecting from the cylinder I at the ends of the rubber sleeve or tube Q?. The rubber sleeve QZ must not tit too tightly, nor too loosely, so that the slightest pressure of air 'from the in- IIO l part of the rod S. The screwplug T is pro- I tribes is provided with a block, Vf, having a Pend of the free end, into which notch the ring side can escape through the apertures Q' tol the outside, and the slightest pressure from the outside perfectly closes the rubber against the groove and prevents the air from passing into the interior of the cylinder. The bottom head, P2, of the cylinder P fits loosely in the wide part of the tube O, and is providedwith a central vertical aperture, p', and with two transverse channels,- 112, crossing each other, and at the end of each transverse channel p2 a vertical slot, p3, is formed. The bottom sur face of the bottom head, P2, of the valve-cylinder P rests upon a series of elastic perforated indiarubber rings, O3, of which the lower one rests on the shoulder O', formed in the tube O. The lever-spout (shown in Fig. 6) consists of a tubular casing, B, made of tin, having itslower end widened, internally screwthreaded, and surrounded by a bronze ring, B', to protect the tin when screwing the spout' on the neck N' of the fountain. A spout, B2, made of pure tin, is screwed on a tubular arm of the casing B. A tinned brass rod, S, passes centrally through the casing B and through a stuffing-box, S', held in the casing directly above the spout projection, which stuffingbox is formed-of a series of rings of rubber, on which a tinued brass washer rests. The end of the rod S projects through a tin screwplug, T, screwed in the upper part of the casing B. A spiral spring, S2, surrounding` the rod S, rests on or is held between the stuffingbox S' and a disk, S", mounted on the upper vided with a rigid arm, T', on the outer end of which a ring, T3, is held loosely. A lever, T2, is pivoted to jaws t, projecting' from the screw-plug T, diametrically opposite the arm T', and the said pivoted leverT2 is provided at the pivoted end with a check-lug, t', adapted to strike against the casing B, to prevent the arm T2 from being raised too high. The arm T'l is provided with a notch, t2, in the upper T can be passed.

If desired, several fountains can be filled from one generator. In this case the generator B is placed on a tripod, which is provided with brackets supporting a circular tin tube, V, which is provided with a series of downwardly-projecting threaded spouts, V', some of which are closed by screw-caps V2. and to others strongrubber tubes WV are coupled by means of screw-collars W', held on tubular blocks W2, on which the ends of tubes are fastened by wire or in any other suitable manner, packing-strips being being interposed between the blocks VZ and the spouts V. One of the threaded neck, VW, adapted to be screwed into the internally-threaded aperture in the block L in the bottom ofthe generator. The ends of the tubes NV are then coupled to the fountains A or A, which can be made spherical, elliptical, or cylindrical in the usual manner. The said fountains A6 are provided with a neck against the neck of the bottle.

surrounded by a threaded sleeve, A7, which is held on the neck by an outwardly-project ing flange ofthe neck, and on `the said sleeve AT a screwthreaded cap, A8, is screwed,which is provided with an upwardly projecting threaded neck, A9, and with a downwardlyprojecting threaded neck, on which a tube, O5, which extends almost to the bottom of the fountain, is secured.

The operationv is as follows: The block N of the fountain A is removed and the Vfountain is filled with water. Vhen the level of the water rises to the bottom tubular extension,M,of the block M, no more water can be poured into the fountain, thus leaving a space in the upper part of the fountain, to permit shaking the water and mixing it with the gas which accumulates above the water. The fountain isthen closed and is securely coupled with the bottom of the generator-vessel B', into which a quantity of water is poured through the spout which is then closed very tightly. As the spout is located near the bottom and at the .side of the vessel B", the vessel B' may only be filled with water to a certain height. A mixture of water and bicarbonate of soda, in the proportion of one pint of water to one pound of bicarbonate of soda, is poured through the neck Bt of the cover B into the vessel B2. Commercial sulphuric acid of 66is then poured into the acid-bottle C'. Y The leaden valve-tube Eis placed on the end of the neck C4 of the leaden bottle C', and the ball Gr'l is soadjusted that itcioses the upper ,opening of the said valve-tube E. Thenthe cap or screw-collar D' is screwed on toihold the tubular valve E Then the acidbox is screwed on the generator, the tube F passing into the vessel B, As the acid-box is screwed down, the rubber ring di is gradually compressed and effeetually closes and packs the joint before the lower endof the rod H has struck the bottom of the vessel B2. As the operator continues to screw down the acid-box, the rod H strikes the bottom of the vessel B, and cannot turn. Thereby the cap G' will be screwed upward into the sleeve F'l and will raise the rod G, therebyI raising the leaden ball G2, which closes the 'upper end of the valve-tube E. Now the acid begins to iiow down through the tubular valve E and through the slot F, and Iinally mixes with the mixture of bicarbonate of soda and water, and thereby generates carbonio-acid gas. The air passing up through the vent c' bubbles up through the sulphuric acid. with gas, so that the pressure onvthe valve E is equal on the inside and outside. The gas in the generator passes into the cup J and through the pipe K down through the perforated tin box Kt', and passes from the same through the water 'in the vessel B', through which water it bubbles, and is thereby Washed 'and cleaned and deprived of any traces of sulphuric acid. It then passes through the tin pipe L, and by its pressure it is forced downward and enters the aperture P4 of the valvecylinder P, then passes through the slots Q',

The tube F is always filled` IOO IIO

raises the rubber sleeve Q2, passes into the space between the valve-cylinder P and the tube O, then passes through the vertical slots p, the transverse channels pt of the bottom head, I, through the bottom aperture, p', and through the tube O to the bottom of the fountain, and then rises and is absorbed by the water. In about a quarter of an hour all the gasis developed. Then the cap J" is unscrewed and the gas escapes through the needle-holeg. Vhen the hissing sound ceases, the cap J is unserewed and the threaded valve or cap JZ is screwed on the pipe K, so that no water orsulphateofsoda mixture can get into the said pipe. Then the acid-box C is unserewed from the generator and well washed, and then the fountain is unserewed from the generator. \Vl.ile doing` this there is no danger ofunscrewing the bleek C, as the threads ofthe block N are made very tlat, and those by which the generator is secured to the fountain are made very steep or oblique. The sulplrate-of-soda solution is then poured off and the generator washed. The fountain is well shaken, so as to mix the gas with the water, and then the lever-spout (shown in Fig. 6) is applied. If the lever T is pressed downward, the rod S presses the valve-eylinderI downward, and thus permits the carbonio-acid water to rise in the pipe O and through the bottom of the aperture N2 in the block N. The earbonic-acid water then rises to the spout R, and can be conducted to any desired place, to be filled into bottles or the faucet of a soda-water fountain, 85e.

The above-described apparatus may be made for one or more gallons ot' soda-water, and the fountains can be of glass surrounded by wire, or if they are of larger size they can be made ot' copper and lined with glass, or ot' any other suitable material. If the fountain is silvered on the inside andthe other parts properly protected, wine, cider, beer, &c., can be charged with carbonio-acid gas.

By means ofthe device shown in Figs. 9 and 10, several fountains can be coupled with a gcncrator and all charged at the same time.

If the several parts ot' the apparatus are all enlarged correspondingly, marble dust or whiting can be used in place of bicarbonate of soda.
